Hmm? Are you using TM beta firmware at first post? Downgrade successful with TFTP?

Yes, disable all ALG and UPNP. It will make your router MORE SECURE.
There are some malware/virus/trojan made use of UPNP for portforwarding and exposing victim system to the Internet.

This C1200v1_eu-up-1.1.3 Build 20180124 rel.52299 firmware is still very prone to uncommanded reboots.

12 hours and reboot
8.5 days and reboot

I'm experiencing 2.4Ghz WiFi is always "Aquiring IP Address..." around evening time.

Currently im using mikrotik. That’s why you are seeing ipv6 feom the forum. I think i have mentioned that the tplink not usable. I cant browse anything. I have disable usb & print sharing.

My main aim is
1) low CPU load
2) works with hypptv
3) ipv6

Currently testing the famous cylindrical router, dlink dir850l router which ............... awesome and far more better than that c1200. ............

~.~ It is well known fact that C1200 will still random reboot, although not that frequent.
Basically, one can expect random reboot once a week.

It is a pity. C1200 hardware is better than DIR-850L.  But unstable firmware is really an issue.

Any high end router that costs more than RM800.

Example : ASUS RT-AC68U ---> Reason = one can flash alternative firmware.....although default firmware is good enough....

-.-...Do you know TP-Link C1200 itself cost about RM350?

And D-Link DIR-850L costs about RM300?

How exactly do you think <RM200 router will perform?    Hate to shatter your hope, but hey...it is life....

Thus, I propose you to check your area for 2.4Ghz wifi.
If it is really congested.....as in 10 - 20 wifi hotspots around, you are screwed.

Plus, some leaky microwave oven can totally screwed 2.4Ghz wifi signal.

Even better, try to connect to C1200 2.4ghz and run some speed benchmark. If it can get 30Mbps, RT-N12HP should be fine.

First analyze your situation.
1. Do your area congested with 2.4ghz wireless signal.
2. Do you need a dual band router?
3. What internet package you're current subscribed to?
4. How many devices connected to the router i.e how many device will stay connected with the router via physical connection and how many devices will stay connected via wireless?
5. What is your budget? If your budget is around rm200, the best router you can get around the price is asus rtn12hp. But is it worth for your home usage?
6. If you're subscribe to between 10 to 50Mbps, then you can buy a single band router. But remember, although your area is not congested, sometime, your house appliances can cause wireless distortion.
7. If you're planning to use or upgrade to higher bandwidth such as 100Mbps, then you need to invest money on a dual band router that comes with gigabit wan+4xlan ports.
8. Where do you place the router? If you staying in a double storey house, you should place the router at upstairs and not downstairs since the wireless signal transmitted downwards and not upwards. and the router should be placed at the center of your house.
9. Your router should always receive firmware upgrades from the manufacturer like asus brand. This is to ensure you don't always have to stick up with the firmware bugs. avoid tplink and dlink brand whenever possible.
10. You should know how to tweak the performance of the router so that you can maximize the performance of the router.

there you go. I always spend some money to test out the routers. And  currently, i am testing dir850l router (tm version). My luck is good when i bought a virgin dir850l which the bos is still seal in the plastics.  . Archer c5 definitely better and only c5v1 supports third party firmware such as ddwrt but ready to lose your 5ghz wireless card / board. 

keep on complaining to them that the wireless not stable and the router keeps rebooting twice or thrice in a day.

P/s: I stated that dir850l (using latest tm firmware, 2.09TM) better than c1200 because I feel it is decent enough for me. I do not emphasize that this router promise you with epic performance. i have 4 laptops, a pc, 5 androids and 1 iphone 7+, and i feel the router can handle the connected device well.

As mentioned by @SilentVampire bro, you can give asus rtn12hp a try.

If you for free then dir850l.
if you want to invest, then pick rt12hp

Reverting to the Beta firmware. The latest v1.1.3 Build 20180124 rel.52299 firmware is terrible for me. Keeps rebooting.

if you replace the c1200 to 850l from tm. i said free. 

when i open the box, the router pre-loaded with tm's latest firmware, 2.09TM. So im currently running the latest firmware.
